Is it true 4g lte is only good for short high speed bursts ?

Not constant high speed.

I noticed this when I do a speed test.

so many external factors like how busy the tower is while you access it. A 5-bar LTE connection to a tower will be unusable when there is, say, a few thousand other people around you trying to use it too. There are only so many time slices available per second per user.
Under ideal conditions on a quiet tower, there would be no reason you would not see sustained high speed throughput.

Thanks makes sense!
